About this file
This is Addendum #2 to the contract documents for the SUNO Boiler Replacement project located at 6400 Press Drive, New Orleans, Louisiana, issued by Parish Engineering, LLC on November 5, 2025. The addendum modifies the mechanical specifications and drawings for the boiler replacement at the Arts & Humanities Building and Gymnasium at Southern University of New Orleans (SUNO), identified as Parish Project No. 25-040. The primary modification requires replacement of drawing sheet M2.0 in its entirety with the attached mechanical details sheet. Additionally, Section 232113 of the specifications regarding chemical treatment has been revised to require coordination of all water treatment with the owner's designated water treatment provider, Thornton, Musso, & Bellemin, Inc., with contact information provided for Jeff LeJeune.
The addendum establishes prior approval requirements for specific manufacturers and product models to ensure compliance with contract specifications. Approved manufacturers include Fulton for hydronic boilers and modulating boiler sequencing systems, Taco or Paterson for air separators, PRM Filtration for magnetic filters/separators, and Taco for compression tanks. The document clarifies that manufacturer acceptance does not waive compliance with plans and specifications, and manufacturers remain responsible for meeting all contract requirements. The replacement drawing sheet M2.0 includes mechanical details encompassing boiler piping diagrams, air control system piping, duct/pipe hanger anchors, and refrigerant pipe support hangers, along with detailed sequence of operation parameters for boiler run and stop conditions, pump interlock provisions, and lead-lag pump operation protocols.

CENTRAL HEATING WATER:
A. RUN CONDITIONS:
a. BOILER SHALL BE IN STANDBY MODE & ENABLE TO RUN UPON A CALL FOR HEATING, INDICATED BY TIME OF DAY SCHEDULE AND OUTSIDE AIR
TEMPERATURE SETPOINT.
b. BOILER SHALL RUN SUBJECT TO ITS OWN INTERNAL CONTROLS & SAFETIES TO MAINTAIN A SUPPLY TEMPERATURE SETPOINT OF 180°F
(ADJUSTABLE).
c. BOILER SHALL NOT BE ENABLED WHEN OUTSIDE AIR TEMPERATURE IS ABOVE 70°F (ADJUSTABLE).
B. STOP CONDITIONS:
a. BOILER SHALL SHUT DOWN AND ENTER STANDBY MODE WHEN NO CALL FOR HEATING, INDICATED BY TIME OF DAY SCHEDULE AND OUTSIDE AIR
TEMPERATURE SETPOINT.
b. BOILER SHALL SHUT DOWN & GENERATE ALARM UPONE RECEIVING A REFRIGERANT LEAK DETECTION STATUS, CARBON MONOXIDE DETECTION OR
HYDROCARBON DETECTION.
c. BOILER SHUT DOWN & GENERATE ALARM SUBJECT TO OWN INTERNAL CONTROLS & SAFETIES & MANUAL BOILER SHUTDOWN SWITCH.
C. BOILER - PUMP INTERLOCK:
a. LEAD HOT WATER PUMP SHALL RUN WHEN BOILER IS ENABLED. UPON PROOF OF FLOW OBTAINED BY CURRENT SENSING RELAY ON PUMP, BOILER
